But that's part of the problem - comments will only show up if there are enough people looking at it to do the endorsing. A single site-wide list of pending comments won't work either - surely the whole point is that comments should be endorsed in the context of the thread?

It also runs the risk that things will only get endorsed if they agree with commonly-held views, and I'll also be interested to see how it effects things like whoishiring.

Some sort of moderation is fine, but I think that in its current implementation, this is a rather ham-fisted approach which will have a detrimental effect on HN.
